拖式混凝土输送泵的泵送部分设计（全套图纸）精品.doc

图书分类号： 密 级： 摘要 HBT60混凝土输送泵是一种将符合泵送条件的混凝土通过水平或垂直铺设的管道连续地输送到建筑施工现场的混凝土输送机械。它被广泛地应用于城建、矿山、电力、能源、交通及其他部门的混凝土建筑工程中。 HBT60混凝土输送泵的两个液压缸分别与两个混凝土输送缸串联，在两个液压活塞驱动下，两个混凝土输送缸在分配阀的控制下，交替地将混凝土吸入和排出。HBT60混凝土输送泵的分配阀为S形管阀，它的一端与输送管接通，另一端则通过摆动与两个混凝土输送缸交替接通，对准哪一个缸口，哪一个缸就向外排出混凝土。同时，另一个缸则从料斗中吸入混凝土。S管阀的摆动是通过对称配置于S管阀回转轴两侧的液压缸推力臂来实现的。 关键词 混凝土输送泵；液压缸；S管阀；分配阀 Abstract The HBT60 concrete delivery pump will be one kind conforms to the transportation condition concrete the pipeline which or vertical will lay down through the level continuously to transport to the construction job location concrete transportation machinery. It widely is applied to the urban construction, the mine, the electric power, the energy, the transportation and in other departments concrete building projects. The HBT60 concrete delivery pump two hydraulic cylinders separately with two concrete transportations cylinder series, under two hydraulic pressure pistons actuation, two concrete transportations cylinder under the operating valve control, in turn and discharge the concrete. The HBT60 concrete delivery pump operating valve is the shape tube valve, its end and the delivery pipe put through, does another end through swing puts through in turn with two concrete transportations cylinder, which cylinder mouth aims at, which cylinder on discharges the concrete to outside. At the same time, another cylinder from center inspiration concrete. S tube valves winging is the valve rotation axis two sides hydraulic cylinder thrust forces realizes through symmetrical arrangement. Keywords Concrete delivery pump Hydraulic cylinder S－tube valve Operating valve 目 录 1 绪论 1 1.1 混凝土输送泵的简介 1 1.2 混凝土输送泵的发展趋势 2 2 混凝土泵技术参数及原理 3 2.1 主要技术参数 3 2.2 主要组成部分 4 2.2.1 分配阀及料斗 4 2.2.2 推送机构 7 2.3 泵送原理 8 3 液压系统 10 3.1 液压系统组成 10 3.1.1 混凝土输送液压系统 10 3.1.2 主泵送油路系统 11 3.1.3 搅拌及冷却液压系统 13 3.1.4 水清洗液压系统 14 3.1.5 摆动系统 14 3.1.6 润滑系统 14 3.2 泵液压系统的设计计算 15 4电气控制系统 23 4.1 动力控制系统 23 4.2 泵送控制系统 24 4.3 有限遥控系统 24 4.4 各元件的功能说明表 24 4.5
